Description

Technical Field

[0001] This utility model relates to the field of steel slag dust treatment technology, specifically to a dust removal mechanism for slag boxes. Background Technology

[0002] In industries such as steel and metallurgy, slag bins are typically used to collect and temporarily store steel slag (such as desulfurization slag, casting residue, and bottom slag) generated during steel smelting for subsequent processing.

[0003] The existing slag box is a semi-open slag box, with a cover on only one side of the main body, while the other side is an open structure. This design leads to dust easily escaping from the openings during slag dumping and water cooling operations, causing fugitive emissions, polluting the environment, and affecting operational safety. Furthermore, the dust collection pipes of the existing slag box are located at the back of the main body, and since dust rises during slag dumping, this design results in low dust collection efficiency. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a slag box dust removal mechanism to solve the problems of low dust collection efficiency and incomplete closure of the structure of the existing slag box dust removal mechanism, which causes fugitive dust emission.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A dust removal mechanism for a slag box includes a cover covering the top of the slag box body. The cover consists of a fixed top cover and a movable top cover. The lower edge of the fixed top cover is fixed to the upper edge of the slag box body, forming an opening between them for convenient slag dumping. A dust removal pipe is provided on the top of the fixed top cover. The movable top cover is rotatably connected to the fixed top cover by a hinge mechanism. The movable top cover is connected to a drive mechanism, which can drive the movable top cover to rotate relative to the fixed top cover to close or open the opening.

[0007] Furthermore, the fixed top cover is composed of a fixed rectangular plate and lateral baffles located at both ends of the fixed rectangular plate. One long side of the fixed rectangular plate is fixed to one long side of the slag box body opening. The two lateral baffles are respectively fixedly installed at the ends of the fixed rectangular plate and the slag box body opening. The movable top cover is a rectangular plate. The movable top cover is rotatably connected to the other long side of the fixed rectangular plate through one long side. The other long side of the movable top cover overlaps with the other long side of the slag box body opening to close the opening. In the overlapping state, the movable top cover and the fixed rectangular plate form an inverted V shape.

[0008] Furthermore, the drive mechanism is connected to the movable top cover via a flexible traction component.

[0009] Furthermore, the flexible traction assembly includes two traction steel wires, one end of each traction steel wire is fixed to the upper surface of the movable top cover, the line connecting the fixing points of the two traction steel wires on the upper surface of the movable top cover is parallel to the axis of the hinge mechanism and is arranged symmetrically from left to right, and the other end is connected to the winch of the corresponding drive mechanism by passing through their respective guide components.

[0010] Furthermore, a support frame is provided on the fixed top cover. The support frame includes four vertically arranged support legs and several support rods fixedly connected to the upper surface of the support legs. The lower ends of two support legs are fixed to the upper surface of the fixed top cover, and the line connecting the two fixed points is parallel to the axis of the hinge mechanism. The lower ends of the other two support legs are fixed to the ground surface area directly opposite the middle of the bottom edge line of the rear side of the slag box. The drive mechanism is set on the ground surface and located between the two support legs. Two sets of guide components are symmetrically installed on opposite sides of the upper surface of the support rods.

[0011] Each guide assembly includes four steering wheels arranged in a rectangular pattern. The first and second steering wheels are arranged along one diagonal of the rectangle, with their axes of rotation parallel to the upper surface of the support rod. The third and fourth steering wheels are arranged along the other diagonal of the rectangle, with their axes of rotation perpendicular to the upper surface of the support rod. One end of each of the two traction steel wires is fixed to the movable top cover, and the other end passes sequentially around the first, third, fourth, and second steering wheels of the corresponding side guide assembly before being wound onto the winch of the corresponding drive mechanism.

[0012] Furthermore, the drive mechanism is equipped with a limit sensor to monitor the length of the wire rewinding. When the length of the wire rewinding reaches a set value, the drive mechanism is triggered to stop working.

[0013] Furthermore, a number of limiting rods are vertically spaced at intervals on the top of the fixed top cover near the edge of the hinge mechanism.

[0014] Furthermore, the hinge mechanism is a hinge shaft or a plurality of hinged hinges arranged at intervals.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The dust removal mechanism for the slag box provided by this utility model, by setting the dust removal pipe at the top of the slag box, can directly suck up dust from above the slag box, thereby maximizing the dust intake into the dust removal device, enhancing the dust removal effect, and reducing the possibility of dust escaping. Simultaneously, with the rotating protective cover, this utility model can be sealed during slag dumping operations and water spray cooling, preventing dust from escaping during operation due to excessive open areas of the slag box, thus transforming fugitive dust emissions into organized emissions.

[0017] 2. This utility model achieves automatic opening and closing of the top cover through the coordinated action of electromechanical components such as electric motor, reducer, and winch, further reducing the need for manual intervention and improving operational safety and dust removal stability.

Detailed Implementation

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Example

[0022] See Figure 1 , Figure 2 This utility model provides a dust removal mechanism for a slag box, including a cover 2 covering the top of the slag box body 1. The cover 2 is composed of a fixed top cover 201 and a movable top cover 202. The lower edge of the fixed top cover 201 is fixed to the upper edge of the slag box body 1, forming an opening between them to facilitate slag dumping. A dust removal pipe 5 is provided on the top of the fixed top cover 201. The movable top cover 202 is rotatably connected to the fixed top cover 201 through a hinge mechanism 3. The movable top cover 202 is connected to a drive mechanism 6, which can drive the movable top cover 202 to rotate and open relative to the fixed top cover 201 to close or open the opening.

[0023] In specific implementation, the fixed top cover 201 is composed of a fixed rectangular plate and lateral baffles located at both ends of the fixed rectangular plate. One long side of the fixed rectangular plate is fixed to one long side of the opening edge of the slag box body 1, and the two lateral baffles are respectively fixedly installed at the ends of the fixed rectangular plate and the short side of the opening edge of the slag box body 1. The movable top cover 202 is a rectangular plate. The movable top cover 202 is rotatably connected to the other long side of the fixed rectangular plate through one long side. The other long side of the movable top cover 202 overlaps with the other long side of the opening edge of the slag box body 1 to close the opening. In the overlapping state, the movable top cover 202 and the fixed rectangular plate form an inverted V shape.

[0024] In practice, the drive mechanism 6 is connected to the movable top cover 202 via a flexible traction component.

[0025] In specific implementation, the flexible traction assembly includes two traction steel wires 7. One end of each traction steel wire 7 is fixed to the upper surface of the movable top cover 202. The line connecting the fixed points of the two traction steel wires 7 on the upper surface of the movable top cover 202 is parallel to the axis of the hinge mechanism 3 and arranged symmetrically from left to right. The other end is connected to the winch of the corresponding drive mechanism 6 by passing through their respective guide components 9.

[0026] In specific implementation, a support frame 8 is provided on the fixed top cover 201. The support frame 8 includes four vertically arranged support legs and several support rods fixedly connected to the upper surface of the support legs. The lower surfaces of two support legs are fixed to the two ends of the upper surface of the fixed top cover 201 parallel to the axis of the hinge mechanism 3. The lower surfaces of the other two support legs are fixed to the ground surface area directly opposite the middle of the bottom edge line of the rear side of the slag box. The drive mechanism 6 is located between the two support legs on the ground surface. Two sets of guide components 9 are symmetrically installed on opposite sides of the upper surface of the support rods.

[0027] Each guide assembly 9 includes four steering wheels arranged in a rectangular pattern, wherein: the first steering wheel 901 and the second steering wheel 902 are arranged along one diagonal of the rectangle, and their axes of rotation are parallel to the upper surface of the support rod; the third steering wheel 903 and the fourth steering wheel 904 are arranged along the other diagonal of the rectangle, and their axes of rotation are perpendicular to the upper surface of the support rod; one end of each of the two traction steel wires 7 is fixed to the movable top cover 202, and the other end passes sequentially around the first steering wheel 901, the third steering wheel 903, the fourth steering wheel 904 and the second steering wheel 902 of the corresponding side guide assembly 9, and then the two traction steel wires 7 are gathered to the winch of the corresponding drive mechanism 6. The reason for this arrangement is that the two ends of the bottom edge of the slag box are located on the ground surface, which makes it impossible to install the drive mechanism 6 on the ground surface, which is located at the two ends of the bottom edge of the slag box. Therefore, in this embodiment, the drive structure is set in the ground surface area directly opposite the middle of the bottom edge of the slag box. Since the fixing point of the traction steel wire 7 and the movable top cover 202 is located near the two ends of the movable top cover 202, this application uses the steering wheel to move the traction steel wire 7 laterally to a position near the middle and then pull it vertically downward to the drive structure, so as to bypass the factory columns and realize the opening and closing of the movable top cover 202.

[0028] In specific implementation, a limit sensor (not shown) is installed on the drive mechanism 6. The limit sensor monitors the length of the wire rewinding. When the length of the wire rewinding reaches a set value, the drive mechanism 6 is triggered to stop working. In this way, by monitoring the length of the wire rewinding, the opening and closing angle of the movable top cover 202 can be indirectly limited, thereby preventing the movable top cover 202 from opening and closing at too large an angle, which would prevent the movable top cover 202 from closing again due to its own weight.

[0029] In specific implementation, a number of limiting rods 4 are vertically spaced at intervals on the top edge of the fixed top cover 201 near the hinge mechanism 3. In this way, when the limiting sensor fails, the opening and closing angle of the movable top cover 202 can still be limited by mechanical limiting, so that it can only open and close between the overlapping position and the vertical position. Because after exceeding the vertical position, even if the traction steel wire 7 is released, the movable top cover 202 cannot return to the original overlapping state by gravity, thereby avoiding the movable top cover 202 opening and closing angle being too large, so that the movable top cover 202 cannot be closed again by its own gravity.

[0030] In specific implementation, the hinge mechanism 3 is a hinge shaft or a number of hinged hinged pages arranged at intervals. When the hinge mechanism 3 is a hinged hinged page, the hinged hinged page includes two mutually hinged pages, one page is fixed to the fixed top cover 201, and the other page is fixed to the movable top cover 202.

[0031] In practice, the number of dust removal pipes 5 can be determined according to the size of the slag box, such as one, two or three pipes.

[0032] Instructions for use: When the movable top cover 202 needs to be opened or closed, power is supplied to the motor of the drive mechanism 6. After the motor of the drive mechanism 6 is powered on, the power is transmitted to the reducer on the drive mechanism 6. The reducer drives the winch to rotate, thereby realizing the winding or unwinding of the traction steel wire 7, which in turn drives the movable top cover 202 to open or close. When the length of the rewound steel wire reaches the set value, the limit sensor transmits a signal to the control cabinet to control the drive mechanism 6 to stop working. When the limit sensor fails, mechanical limit is achieved by the limit rod 4 on the fixed top cover 201 to prevent the movable top cover 202 from opening or closing too much, which would prevent the movable top cover 202 from being unable to close again.

[0033] When steel slag needs to be poured into the slag box, the drive mechanism 6 first drives the traction steel wire 7 to open the movable top cover 202. Then, high-temperature steel slag is poured into the slag box, and water is sprayed onto the steel slag in the slag box at the same time to cool it down, which will generate a large amount of water mist. The drive structure drives the traction steel wire 7 to close the movable top cover 202, and the large amount of water mist and dust generated is sucked away through the dust removal pipe 5 at the top of the fixed top cover 201, thereby ensuring the cleanliness of the site environment.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
